PIPE-VISE.

SPECIFICATION forming part of Letters Patent N 0. 709,944, datedSeptember 30, 1902. Application filed January 3, 1902. serial No.88,272. (No model- To alt whom it may concern:

Be it known that we, JOHN B. VOGELBAOH and THOMAS GRAY, citizens of theUnited States,and residents of Brooklyn,iu the county of Kings and Stateof New York,.have invented certain new and useful Improvements inPipe-Vises, of which the following is a specification.

The invention relates to improvements in pipe-Vises; and it consists inthe ,novel features and combinations of parts hereinafter described, andparticularly pointed out in the claims.

The object of ourinvention is to provide an efficient portable visewhich may be carried by 'a workman and conveniently used withoutrequiring the presence of fastening devices for securing the vise to asupport.

Theinvention will be fully understood from the detailed descriptionhereinafter presented, reference being had to the accompanying drawings,in which- Figure 1 is a front elevation of a pipe-vise constructed inaccordance with and embodying the invention, the vise being shown asgripping a piece of pipe and as having applied thereto a handle or rodor tube by which the vise may be suspended from the knees of aworkman,said handle, rod, or tube being detachable and preferably beingsimply apiece of pipe passed through the receivingsleeve formed on thevise-frame. Fig. 2 is a bottom view of same, and Fig. 3 is a sectionalView on the dotted line 3 3 of Fig. 1.

In the drawings, designates the main frame of the vise, said frame beingformed at one edge with the sleeve 11 and at its opposite ends with thearms 12 13, the arm 13 having the usual threaded boreto receive thescrew 14, which carries the movable jaw 15 of the vise. The outer end ofthe screw It will be provided with a convenient handle 16 to facilitatethe turning of the screw. The end of the screw 14 is in the usual mannerswiveled in the two-part frame 17, between the parts of which the jaw 15is secured by means of a bolt 18 and which engage the guiding-ribs 19,formed longitudinally along the main frame 10. The rotation of the screw14 results in the usual longitudinal movement of the frame 17 and jaw15, and the engagement of the frame 17 with the ribs 19 serve todirectthe movementof thejaw 15 and compel the due longitudinal travel ofsaid aw. 4

The arm. 12 of the frame 10 forms an inclosure for the jaws 20, therebeing two of the jaws 20 set into the recesses 21, formed in theopposite sides of the arm 12 and held therein by means of the bolt 22,said bolt serving to clamp the jaws 20 againstthe walls formed by therecesses 21. There are two of the jaws 20 and but one jaw 15, and thejaw 15 is adapted to travel ona line centrally between the jaws 20, soas to firmly grip the pipe 23 in the manner illustrated in Figs. 1 and2. The jaws 15 20 at their facing edges are recessed in the usual mannerand are removable. The manner of applying and securing the jaws 20 tothe frame 10 is particularly desirable, since the edges of three sidesof the jaws are firmly supported by the walls of the recesses 21 andsince by means of a single bolt 22 the said jaws may be conveniently,quickly, and rigidly secured in position.

The sleeve 11 is of elongated form and is integral with the frame 10,and the said sleeve 11 is of special importance; since thereby the visemay be held suspended from the knees of a workman by means of a handleor ordinary piece of pipe 24, which may be freely passed through thesleeve 11 and rest at its ends upon the knees of a workman while thevise-frame 10 is suspended between said knees.

In Fig. l we illustrate the manner of employing the vise in locationswhere permanent fixtures therefor are not to be found, the vise thenbeing supported upon the knees of the workman by means of a piece ofpipe or other handle 24. In the employment of thevise in the mannerdenoted in Fig. 1 it may be assumed that the workman will sit upon a boxor other'convenient seat and rest the ends of the piece of pipe orhandle 2+t upon his knees with the vise-frame suspended between hisknees. The pipe 23 to be operated upon will be gripped by the jaws 15 20and may rest upon the box upon which the workman may be seated, theworkman sitting upon said pipe. The workman or attendant who willperform the threading or cutting of the pipe 23 will proceed with hiswork in the usual manner and with the usual tools, while the l for themovable one of said jaws, combined workman holding the vise upon hisknees will simply be compelled to steady the pipe or handle 24 upon hisknees and see that the action of the cutting-tool upon the pipe 23 shallnot raise said handle therefrom. To have found by experience that verylittle effort is required to retain the handle or pipe 24 upon the kneeswhile the workman is threading or cutting the pipe 23, and in thisregard the invention is of special importance, since it enables theconvenient manipulation of the pipe 23 with a minimum amount of efforton the part or the person holding the vise. The handle or pipe 2ifurnishes a long leverage for enabling the holding of the vise upon theknees of a workman, and the sleeve 11 is of elongated form and has afirm hearing against the handle or pipe 24. It is not intended that theworkman shall necessarily carry with him the handle or piece of pipe 24,since in the majority of instances a suitable piece of pipe or rod willbe found where the work is to be performed for use as a handle with thesleeve 11. It is one of the purposes of the present invention that thevise shall be without complication and convenient to be carried by theworkman with his other tools, it being our object to supply a lightportable vise which may be conveniently carried about and convenientlyoperated without requiring special fixtures for its support.

What we claim as ourinvention, and desire to secure by Letters Patent,is-- 1. The portable vise comprising the frame, the gripping-jaws, andthe operating-screw with the longitudinal sleeve 11 at the outer edge ofsaid frame and parallel with the axial center of said screw and adaptedto receive thehandle 2 L; substantially as setforth.

2. The portable vise comprising the frame, the operating-screw, thesliding frame 17 carried by said screw, and the jaws carried by saidframes and recessed on their'edges to effect the requisite grippingaction, combined with the sleeve 11 constituting a part of said frameand adapted to receive the piece of pipe or handle by which the vise maybe suspended; substantially as set forth.

3. The vise comprising the frame,operatingscrew, sliding frame 17carried by said screw, jaw carried by said frame 17, and the jaws 20,and the vise-frame having the recesses 21 to receive said jaws 20, andsaid jaws being drawn toward one another and held in said recesses bythe bolt 22, combined with the sleeve 11 extending longitudinally of thevise-frame and at outer edge thereof, said sleeve 11 being adapted todetachably receive a handle 24 by which the vise maybe suspended betweenthe knees of a workman; substantially as and for the purposes set forth.
